"sounds more like a third party memory card o.o"
Actually, my 3rd Party Datel Memory Card saves fine, it just doesn't save for all games... like Lost Colors...

Thats why I bought the crappy 8MB one that lost its memory already... in 1 WEEK...

My PS1 Card is worse, it loses its memory (Aka corrupts the Data) Within a few hours of loading it up...

I have the worst luck with these things, I get all the defects...
